These tasks: V (the volume of the cast iron sculpture under consideration) = 2500 cm3 (in the SI system V = 2500 * 10-6 m3).
Constants: ρh (density of cast iron) = 7000 kg / m3.
We calculate the mass of the cast-iron sculpture under consideration by the formula: m = ρh * V.
Calculation: m = 7000 * 2500 * 10-6 = 17.5 kg.
Answer: The cast-iron sculpture in question has a mass of 17.5 kg.
